SHOE-SHAPING MACHINE.

Specification of Letters Patent.

Patented May 28, 1918.

To all whom it may concern:

Be it known that I, EDWARD ERIOKSON, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvemenst in Shoe-Shaping Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to'machines for use in the manufacture of shoes for shaping portions of the shoe stock in such manner as to improve the appearance and the durability of the finished shoe, and is of particular utility as embodied in a machine for operating upon the bottom portion of a welt shoe after the lasting operation to prepare the shoe for the attachment of the welt and the sole.

In the usual operation of lasting a Welt shoe the upper is wiped inwardly over the margin of the innersole around the toe and the heel by the lasting instrumentalities, and is then secured in lasted position at the toe by a binding wire and at the heel by lasting tacks which are permanent and should be fully driven and clenched on the metal heel plate of the last, while at the sides of the last the upper is secured in position by par tially driven temporary tacks. The lasting instrumentalities operate to conform the upper to the last and to force it against the lip of the innersole and into the angle between the lip and the feather edge of the innersole. In the manufacture of the better grades of shoes, however, it is frequently found desirable to use means in addition to the lasting instrumentalities for molding and creasing the upper permanently in the angle between the lip and the feather edge of the innersole, particularly at the toe end of the shoe, in order that the welt may be secured as closely as possible to the innersole in the welt attaching operation. The desirability of using such means for shaping the upper at the toe end of the shoe is increased by the fact that the folds or creases in the margin of this portion of the upper add to the difficulty of conforming the upper to the innersole lip and feather. A machine for operating upon an upper in this manner is disclosed in United States Letters Patent No. 1,009,721, granted upon the application of James Cavanagh, Nov. 28, 1911.

In lasting and securing the upper at the heel seat the object is to conform the upperas closely as possible to the face of the inner sole so as to provide a flat seat to which the heel end of the sole may be closely attached. It is, accordingly, the usual practice, after the upper has been wiped in and secured at the heel end, to pound the heel seat with a hand tool in order to flatten the creases in the margin of the upper and drive the lasting tacks down evenly and clench them se curely upon the heel plate.

An important object of this invention is to eliminate the necessity for pounding the heel seat by hand and to provide a machine by the use of which the heel seat beating operation and the above described operation of molding or creasing the upper may be quickly and effectively performed. To this end, an important feature of the invention consists in the provision of novel means for beating the heel seat of a lasted shoe and for forming the upper in the angle between the innersole lip and the feather, comprising a unitary construction and arrangement by the use of which either operation may be performed at the will of the operator and both operations may be readily performed in succession upon the same shoe. The invention is herein shown as embodied in mech anism including a tool adjustable to difierent positions for use in performing the different respective operations. It will be understood, however, that the invention is susceptible of various embodiments and that in its broader aspects it is not limited to the illustrated constructional details.

The above and other features of the invention, including certain details of construction and combinations of parts, will now be described with reference to the accompanying drawings and pointed out in the claims.

In the drawings:

Figure 1 is a view in side elevation, with portions in section, of a machine in which the invention is embodied, and

Fig. 2 is a view of the machine in front elevation, with a portion in section on the line 22 of Fig. 1, the operative parts being shown in a different relation.

2. A machine of the class described having, in combination, means for forming an upper in the angle between the lip and the feather edge of an innersole and means for beating a shoe upon the heel seat, the machine being constructed and arranged for adjustment to bring either of said means alternatively into convenient position for treating a shoe.

A machine of the class described having, in combination, a tool adapted to beat the heel seat of a shoe and shaped also to crease an upper in the angle between the lip and the feather edge of an innersole, and means for operating said tool, the tool being adjustable to different positions for heel seat beating and for upper creasing respectively.

at. A machine of the class described having, in combination, a tool formed with a beating face adapted to operate upon the heel seat of a shoe and shaped at the edge of said face to form an upper in the angle between the lip and the feather edge of an innersole, and means for operating said tool, the tool being adjustable to present said face in either a substantially horizontal or in an inclined position.

A machine of the class described having, in combination, a shoe beating tool having a substantially flat beating face, and means for imparting operative movements to said tool, the tool being pivoted for man ual adjustment to change the angular relation of the plane of its beating face to the line of its operative movement.

6. A machine of the class described having, in combination, a shoe beating tool arranged for movement in a substantially vertical path at the front of the machine, and means for operating said tool, the tool being adjustable manually to present its beating face in either a substantially horizontal position or on an incline sloping upwardly toward the rear of the machine.

7. A machine of the class described having, in combination, a tool carrier, a tool mounted on said carrier in position to beat downwardly upon a shoe and formed with a substantially flat face adapted to beat the heel seat of a shoe and with an edge adapted to crease an upper in the angle between the lip and the feather edge of an innersole, and means for operating the carrier to impart beating movements to the tool, the tool being adjustable relatively to said carrier to present either its flat face or its edge in position for downward beating.

8. A machine of the class described hav ing, in combination, a tool carrier, a tool mounted on said carrier and having a substantially flat beating face, and means for operating the carrier to impart beating movements to the tool, the tool being adjustable relatively to the carrier at the will of the operator to present said face in either a substantially perpendicular or an inclined relation to the line of movement of the tool.

9. A machine of the class described hav ing, in combination, a tool carrier, a shoe beating tool on said carrier, means for operating the carrier to impart beating movements to the'tool, the tool being mounted for turning movement relatively to the carrier to change the angular relation of the plane of its beating face to the line of its beating movement, and manually operative means for turning the tool.

10. A machine of the class described having, in combination, a tool carrier, a shoe beating tool on said carrier, and means for operating the carrier to impart beating movements to the tool, the tool being mounted to turn relatively to the carrier about an axis inclined to the line of its beating movement and having a beating face inclined to the axis of said turning movement.
